In the present embodiment, an air inlet passage 31 and a floater compartment 32 which are communicated with each other are provided in the respiratory pipe 3, the air inlet passage 31 is communicated with the facial mask 1, an air inlet hole 321 is provided on the outer side wall of the floater compartment 32, a floater 33 is provided in the floater compartment 32 and composed of a floater upper cap and a floater lower cap, featuring in a capsule shape.

In the present embodiment, a silicone waterproof pad 34 is provided at the top of the respiratory pipe 3, and the inner upper end of the facial mask 1 is provided with a first one-way air inlet valve 8 communicated with the respiratory pipe 3, the first one-way air inlet valve 8 allowing only external air from the floater compartment 32 into the air inlet passage 31 and not allowing air or exhaust gas to flow backward.

In the present embodiment, the facial mask 1 includes a facial mask frame 101, a facial mask lens 102 and a silicone cover 103, the facial mask lens 102 and the silicone cover 103 being fixed together through the facial mask frame 101 and forming a facial compartment 111 and a nasal compartment 112. Air inlet holes are provided on both sides of the nasal compartment 112, a second one-way air inlet valve 9 is provided over the air inlet hole, and the nasal compartment 112 is communicated with the facial compartment 111 and the respiratory pipe 3 through the second one-way air inlet valve 9 to form an independent inhalation passage. This configuration enables external air to enter the nasal compartment 112 through the independent inhalation passage formed by the air inlet passage 31, the facial compartment 111 and the second one-way air inlet valve 9 for breathing of a user, and smooth breathing of the user is ensured.

In the present embodiment, both sides of the facial mask frame 101 are provided with exhaust holes, one-way exhaust valves 10 are provided over the exhaust holes, and the one-way exhaust valves 10 are communicated with the nasal compartment 112 through exhaust passages provided on the inner sides of the facial mask frame 101 to form an exhalation passage. Both sides of the facial mask frame 101 are provided with exterior ornaments 11 corresponding to the one-way exhaust valves 10, and the exterior ornaments 11 are provided with ventilation holes. This configuration enables the exhalation passage to be independent being outside of the inhalation passage, exhaust gas is discharged from the exhaust passage and the one-way exhaust valve 10 through the ventilation holes of the exterior ornaments 11 on both sides of the facial mask frame 101, hence mixing of fresh air and the exhaust gas is avoided, and smooth breathing of a user is guaranteed.

In the present embodiment, a drain hole is provided at the bottom of the facial mask 1, and a one-way drain valve 12 and a drain cap 13 are provided over the drain hole. This configuration allows water to drain through the one-way drain valve 12 and the drain cap 13.

After use, the respiratory pipe 3 is pulled out and folded in the facial mask 1, so that it's convenient to carry the respiratory pipe 3 and the possibility to lose it is reduced;

2. a capsule floater design: when the respiratory pipe is submerged in water, the floater 33 floats upwards automatically, the semi-circle head of the floater 33 is tightly attached to the silicone waterproof pad 34, and the capsule floater with significant buoyancy is more perfect in sealing and waterproof effect to prevent being choked by water entering the respiratory pipe 3; 3. an ventilation design: 1) when a user inhales wearing the full face dive mask, fresh air enters the facial compartment 111 through the respiratory pipe 3 and the first one-way air inlet valve 8, and then enters his nose through the air inlet holes on both sides of the nasal compartment 112; 2) and during exhalation, second one-way air inlet valves 9 on both side of the facial compartment 112 act to prevent exhaled exhaust air from escaping through the facial mask compartment 112 into the facial mask compartment 111. Meanwhile, the first one-way air inlet valve 8 in the facial compartment body 111 prevents air passing herethrough, so that the exhaled exhaust gas is forced to be led to two side exhaust passages on the side surface of the nasal compartment 112, and discharged out of the full face dive mask through side exhaust holes.
